I mean, we would have to pull out of azure completely. Today we spend millions of kroner there every year.
It would also leave a very sour taste for going back to US based companies if this is rectified at a later stage of fear of a similar event.
I predict EU firms will get over it unless there are regulatory reasons they can't. Any EU company with a US presence is already vulnerable to DoJ lawsuits and can be directly compelled.
Just to demonstrate the kind of hell we have to go through (today) when we look at cloud services for storing personal data.
This is the recommended checklist from the Data Protection Authority in Norway when look at new cloud sources. By default we can't use anything outside the EEA, however there have been some agreements with e.g. US (safe harbour). This ruling will effectively eliminate the safe harbour agreements the EU/EEA has with the US.
